[R] strsplit (regex)

[stephen sefick]

#how do I break these up into first two letters (RM), number, and then
the last part
#is there an easily accessible regex tutorial on the internet?

Let's not spend our time and resources thinking about things that are
so little or so large that all they really do for us is puff us up and
make us feel like gods.  We are mammals, and have not exhausted the
annoying little problems of being mammals.
